STEANl--BOILER BLOW-OUT OR CLEANER.

Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed February 20,1906- Serial NO- 302.041.

ments in Steam-Boiler Blow-Outs or Clean-l ers,l of which the followingis a specification. My invention relates to steam-boiler blowouts orcleaners.

The object of the present invention is the provision of a simple,durable, and inexpensive device adapted to be positioned within thewater-legs surrounding the lire-box of a steam-boiler of a traction,stationary, or locomotive engine and utilized to blow out the sedimentunder the steam-pressure.

The invention contemplates the provision of an improved device of thecharacter set forth, as-will fully appear from the followingdescription, while the novel features of the invention are set forth inthe appended claims.

In the accompanying drawings, Figure l is a perspective view showing howthe invention may be applied to a boiler; Fig. 2, an enlarged horizontalsection on line 2 2 of Fig. l; Fig. 3, a cross-section on line 3 3 ofFig. 2; Fig. 4, a perspective detail of the complete invention; Fig. 5,a detail of the inner or rotatable tube; Fig. 6, a longitudinal sectionof Fig. 4, and Fig. 7 a detail section on line 7 7 of Fig. 4.

An ordinary boiler, such as might be used for a traction, stationary, orlocomotive engine, is shown at 1. The present invention is located inthe lower part of the water-legs 2, surrounding the fire-box 3, as thesediment in the steam-boiler collects at these points.

The numerals 4 designate outer tubes disposed horizontally at thebottoms of the four water-legs 2, said tubes .having elongated or moreor less elliptical openings 5 in their tops, and they are rigidlysecured in position by being screwed through the walls of the fire box,and on their outer ends are screwed caps 6, which are provided withblow-off cocks 7. Integral with or connected to the upper faces of thetubes 4 and resting against or connected to the walls of the water-legsare deflecting flanges or members 8, whereby the sediment is caused togravitate through the openings 5.

Located within and snugly fitting the outer tubes 4 are the innerrevoluble tubes 9, which are provided with openings 10, corresponding tothe openings 5 and adapted to register therewith. The inner tubes 9 alsohave blow-out holes or openings l1, which may be brought into alinementwith the blow-off cock 7 when the inner tubes are turned or reversedfrom their normal position; but when in normal position the opening llof each tube 9 is closed by the cap 6. The inner tubes 9 haveturn-handles l2 secured thereto which pass throughthe caps 6.

Thel ends 13 and 14 of the outer and inner A tubes are open, so that thewater is in constant communication with the interiors of the tubes 9.All of the joints may be suitably acked.

Or inarily the inner tubes 9 are positioned with the openings l0uppermost and in regis- -ter with the openings 5, so that the blow-offports 1.1 are closed, although the water has acl cess to the interiorsof the tubes 9. I/Vhen in this position, the sediment passes through theopenings 5 and. 10 and accumulates in the interior of the tubes 9; butwhen it is desired to blow out the accumulations the engineer or firemanturns the handles 12 until the ports l1 are in registerwith therespective blow-off cocks 7. Any suitable means may be employed forlimiting this turning action. When the tubes 9 or such tube as may beturned become reversed, the water under the pressure of the steam blowsout the accumulations within the pipes 9 through the blow-out cocks 7,assuming that the latter have been opened. After the sediment has beeneliminated the tubes 9 are turned back tovtheir former position and theblow-out cocks 7 closed. e

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, .is-

l. Ina steam-boiler blow-out or cleaner, the combination with an outertube having an opening for the elimination of the sediment from saidtube and also open for the passage of the sediment to its interior, ofan inner movable tube located within the outer tube aforesaid and opento receive the sediment within itself and also provided with avoiding-opening which may be broughtlinto communication with theelimination-opening ofthe outer tube by moving said inner tube.

2. In a steam-boiler blow-out or cleaner, the combination with an outertube having an opening for the elimination of the sedi- IOS ment fromsaid tube and also open for the passage of the sediment to its interior,of an inner rotary tube located within the outer tube aforesaid and opento receive the sediwithin itself and also provided with avoiding-opening which may be brought into .communication with theelimination-openitng) of the outer tube by turning said inner 3. In asteam-boiler blow-out or cleaner,

the combination with an outer tube having an opening for the eliminationof the sediment from said tube and also provided withthe combinationwith an outer tube having an opening for the Aelimination of thesediment from said tube and valso provided with openings for thereception of the sediment, of'

an inner rotatable tube located within the vouter tube and havingopenings normally :registering with the sediment-receiving openings inthe outer tube and also provided with Va voiding-opening, said innertube being adapted for rotation to throw its openings out of registerwith those of the vouter tube and vto place the voiding-opening incommunication with the elimination-opening of the outer tube.

5. In a steam-boiler -blow-out or cleaner, 'the combination with anouter tube having an opening for the elimination of the sediment andopen ferthepassage of the sediment 'to its interior, of .asediment-defiector for deflecting the sediment to the receiving-openingof the outer tube, and an inner movable ltube located within the outertube aforesaid and open to receive the sediment within itself andprovided with a voiding-opening which may be brought into communicationwith the elimination-opening of the outer tube by moving said innertube.

6. In a steam-boiler blow-out' or cleaner, the combination with an outertube having an opening for the elimination of the sediment and open forthe passage of the sediment to its interior, of a sediment-deliectorcomprising members which converge toward said outer tube to direct thesediment to the sediment-receiving opening thereof, and an inner movabletube located within the outer tube aforesaid and open to receive thesediment within itself and provided with a vo1`ding-opening which may bebrought into communication with the' eliminationsopening of the outertube by moving said inner tube.

7. In a steam-boiler blow-out or cleaner, the combination with awater-leg of the fire.- boX, of an outer tube disposed in the lowerportion ofthe water-leg and having a sediment-receiving opening-and alsoa sedimentelimination opening, and an innermovable tube located withinthe outer tube aforesaid v and provided with a voiding-opening which maybe brought `into communication with the elimination-opening of the outer'tube by moving said inner tube.

8. Ina steam-boiler blow-out or cleaner, the combination with awater-*leg of the reboX, of an outer tube disposed in the lower portionof the water-leg and having a sediment-receiving opening and asedimentlelimination opening, Van inner movable `tube located withinvthe outer tube aforesaid and provided with a voiding-opening which maybe brought into communication with Vthe elimination-opening of the outertube 4by moving said inner tube, and a sediment-'deiiector comprisingmembers `converging from the walls of the water-leg toward the outertube and adapted to direct the sediment to the sediment-receivingopening of said 'outer v tube. In testimony whereof I 'hereunto affix mysignature in presence 'of two witnesses.
